STA2 - Anemometer Hot Wire

Ditch the hood.


Anemometer Hot Wire

Ditch the hood.

In-duct air balancing with fast response time
Minimizes turbulence effect
Hands free testing
96.5 cm (38″) telescoping probe in in-duct traversing
Dual display shows combo of real-time CFM, air velocity, or temp

The STA2 is a Hot-wire Anemometer built for the HVACR professionals’ air balancing needs. The compact probe tip makes measuring air velocity directly in the duct a breeze. It’s great for traversing a duct and automatically calculating CFM without the hassle and expense of a bulky hood. The 96.5 cm (38″) telescoping probe’s laser etched ruling and flattened edges allows techs to locate proper measurement points within a duct, and ensures that the probe is properly aligned.

This in duct hot-wire anemometer quickly calculates CFM from air velocity and free area. And with the intuitive interface, the STA2 makes it easy to capture the correct data.
